The following testcase FAILs, because replace_rtx replaces a REG with CONST_WIDE_INT inside of a SUBREG, which is an invalid transformation because a SUBREG relies on SUBREG_REG having non-VOIDmode but CONST_WIDE_INT has VOIDmode. replace_rtx already has code to deal with it, but it was doing it only for CONST_INTs. The following patch does it also for VOIDmode CONST_DOUBLE or CONST_WIDE_INT. 2022-04-22 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/105333 * rtlanal.cc (replace_rtx): Use simplify_subreg or simplify_unary_operation if CONST_SCALAR_INT_P rather than just CONST_INT_P. * gcc.dg/pr105333.c: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
